abstract = {Grape seeds are a copious part of the grape pomace produced by wine and juice industry
and they represent an interesting source of phenolic compounds. Proanthocyanidins (PAs) are the
main class of grape seed phenols and are important dietary supplements for their well-known
beneficial properties. In this study enriched extracts obtained from Chardonnay and Pignoletto grape
seeds were characterized for their proanthocyanidins and other minor phenolic compounds content
and composition. Seed PAs were fractionated using Sephadex LH-20, using different ethanol aqueous
solutions as mobile phase and analysed by normal phase HPLC-FLD-ESI-MS. Monomers, oligomers
up to dodecamers and polymers were recorded in all samples. For both cultivars, the extracts showed
a high content in PAs. The determination of other phenolic compounds was carried out using a
HPLC-QqQ-ESI-MS and Chardonnay samples reported a greater content compared to Pignoletto
samples. Contrary to PAs fraction, extracts obtained with ethanol/water 50/50 (v/v) presented a
significant higher phenolic content than the others.},
